Troubleshooting ball mill simulation

Continuing the discussion from Thanks for spending time with us:

A lot to learn - which makes it addictively fun.

I am running into trouble with the simulation of ball mills. They show only as flat endmills. I’ve uninstalled Carbide Create and reinstalled. The version I have is Build 464, Built on: 2020-03-26. No change in the simulation.

How do I move past this one ?

This is a limitation of current versions of Carbide Create — I’m pretty sure older versions didn’t have this limitations and we’ve put in for it to be restored.

So its it a bit of guesswork then ?
Trial and error with back and forth running test jobs on the machine and adjusting ?

At this time, yes. But it’s more math than guesswork — I usually leave a step-shape and then trim it to round with the ball-nosed endmill, see:
